I don't work at a FAANG company, nor have I ever been to SV, nor do I know anyone who works at one of the many enormous tech companies around SV.
In the TV show Silicon Valley they have characters who sit around unassigned doing nothing at the Google-like company in the show. Does this actually happen? Are there people hired at these companies who just don't have a project? Its entirely feasible that Google could afford to do this just to create a dearth of engineers in the area.
The show is (by design) over the top. But there is a piece of truth in it. That’s why it’s funny for everyone who has been at these companies because everyone can see real-life resemblances.
Before someone downvotes me: I am implying that SOME people are like this. By no means the majority or god-forbid everyone. Resting till vesting is a real thing though.
